Simplify (2^(-2) x 5^(-2)). Give the answer as a fraction.

1/100. 2^(-2) = 1/4 and 5^(-2) = 1/25, so the product is 1/4 × 1/25 = 1/100. (Or (2x5)^(-2) = 10^(-2) = 1/100.)

Simplify $(2^{- 2} \times 5^{- 2})$ . Give the answer as a fraction.

Class 8Exponents and PowersExponents and Powers

2^{- 2} = \frac{1}{4}

and

5^{- 2} = \frac{1}{25}

, so the product is

\frac{1}{4} \times \frac{1}{25} = \frac{1}{100}

. (Or

(2 x 5)^{- 2} = 1 0^{- 2} = \frac{1}{100} .

)

Answer: A)

\frac{1}{100}
