Jharne De and Ranjana Kumar Solutions for Chapter: Exponents or Powers, Exercise 5: Test Paper 1

Write the reciprocal of the following: ${\left(-m\right)}^{-6}$

Evaluate: ${\left[{\left(\frac{1}{2}\right)}^3+{\left(\frac{1}{4}\right)}^2\right]}^{-1}$

Write the multiplicative inverse of 153+122+103-1.

Write the additive inverse of ${\left(\frac{5}{2}\right)}^{-3}+{\left(\frac{3}{2}\right)}^{-2}$.

By what number should ${\left(\frac{3}{5}\right)}^{-3}$ be divided so that the quotient is ${\left(\frac{1}{15}\right)}^{-2}?$

By what number should ${\left(\frac{7}{6}\right)}^{-2}$ be multiplied to get ${\left(\frac{3}{14}\right)}^2$?

If $\frac{a}{b}={\left(\frac{9}{7}\right)}^{-3}÷{\left(\frac{3}{7}\right)}^1$, then find the value of ${\left(\frac{a}{b}\right)}^2$.

Simplify: ${\left(2^{-1}-3^{-1}\right)}^{-1}+{\left(2^{-1}-4^{-1}\right)}^{-1}$.
