R S Aggarwal Solutions for Chapter: Algebraic Expressions, Exercise 1: EXERCISE 8A

Writing ($y \times y \times y \times ... 20$ times) in the exponential form, we get, $y^k$. Find $k$.

If the exponential form of $14 \times a \times a \times a \times a \times b \times b \times b$ is $14a^x{b}^y$, then $x+y$ is

Writing $6\times x\times x\times y\times y$ in the exponential form, we get, $6x^2{y}^k$. Find $k$.

Writing $3 \times z \times z \times z \times y \times y \times x$ in exponential form, we get, $3x{y}^2{z}^k$. Find $k$.

If the product form of  $x^2{y}^4$ is $x\mathit{\times }k\mathit{\times }y\mathit{\times }y\mathit{\times }y\mathit{\times }y$, then $k$ is

$6y^5$ in the product form is $a\times \mathrm{y}\times \mathrm{y}\times \mathrm{y}\times \mathrm{y}\times \mathrm{y}$. Find $a$.
