Geometric Mean

Marks of a student in Maths and science is $147$ and $192$ out of $200$. Find the geometric mean of the marks obtained by student.

What is the geometric mean of $4$ and $16$?

Find the geometric mean of $4$ and $3$.

If $n$ geometric means be inserted between $a$ and $b$ then their product is 

If the AM between $\mathrm{‘}a\mathrm{’}\mathrm{ }\mathrm{a}\mathrm{n}\mathrm{d}\mathrm{ }\mathrm{‘}b\mathrm{’}\mathrm{ }$ is twice as greater as the GM, then the value of $\frac{a}{b}$ is

$\sin A,\sin B,\sin C\mathrm{ }$ are in G.P, $\mathrm{ }$ roots of $\mathrm{ }{x}^2+2xcotB+1=0$ are always:

If $m \text{is the A. M.}$ of two distinct real numbers $l \text{and}\mathrm{ }n\left(\mathrm{ }l,\mathrm{ }n>1\right)$, and $\mathrm{ }{G}_1\mathrm{ },G_2 \text{and} G_3\mathrm{ }$ are three geometric means between $1$ and $n,$ then value of $\mathrm{ }\mathrm{ }{G}_1^4+G_3^4+2G_2^4$ is

If $A_1,A_2$ are two A.M.s $G_1,G_2$ are two G.M.s and $H_1,H_2$ are two H.M.s between two numbers, then $\frac{A_1+A_2}{H_1+H_2}$ is equal to

If $a$ be the $\mathrm{A}\mathrm{M}$ between $b$ and $c \& GM’s$ between $b$ and $c$ are $G_1$ and $G_2$, and ${G_1}^3+ {G_2}^3= k abc$ then value of $k$ is

If $f\left(x\right)={\cos }^{2}x+{\sec }^{2}x$, then

Let $a,b,c$ are in GP and $4a,5b,4c$ are in AP such that $a+b+c=70$, then value of $b$ is

Let $G$ be the geometric mean of two positive numbers $a$ and $b$, and $M$ be the arithmetic mean of $\frac{\mathrm{1}}{a}$ and $\frac{\mathrm{1}}{b}$. If $\frac{\mathrm{1}}{M}$: $G$ is $4:5$, then $a:b$ can be

Find the value of $\text{'}n\text{'}$ so that $\frac{a^{n+1}+b^{n+1}}{a^n+b^n}$ may be the geometric mean between $a$ and $b$.

If $a, b, c, d$ are positive real numbers such that $a + b + c + d = 2$, then $m = (a + b) (c + d)$ satisfies the relation
