Question

Evaluate :
. Using laws of exponents evaluate & write in exponential form:
i.
2²x 3⁴x 2⁵
2⁴x 3²
ii.
5⁴ x 7⁵
4⁹x 5²​

Answer 1

Step-by-step explanation:

I) (2²x 3⁴x 2⁵) / (2⁴x 3²)

= 2^(2+5-4) x 3^(4-2)

= 2^3 x 3^2

ii) (5⁴ x 7⁵) /(49x 5²)

= (5^4 x 7^5) / (7^2 x 5^2)

= 5^(4-2) x 7^(5-2)

= 5^2 x 7^3
