Answer 1

Answer:

Step-by-step explanation:

10² *  (- 5)³ * 9⁰ / (-1)⁵¹ * (-2)² * (5)⁴

By law of exponents,  a⁰ = 1;

=> (2 * 5)² * (-1 * 5)³ * 1 / (-1)⁵¹ * (-1 * 2)² * 5⁴

=> 2² *  5² * (-1)³ * 5³ /  (-1)⁵¹ * (-1)² * 2² * 5⁴

=> 2² *  5²⁺³ * (-1)³ / (-1)⁵¹⁺² * 2² * 5⁴   (∵ xᵃ  * xᵇ = xᵃ⁺ᵇ )

=> 2² * 5⁵ * (-1)³ / (-1)⁵³ * 2² * 5⁴

=> 2²⁻² * 5⁵⁻⁴ / (-1)⁵³⁻³   (∵ xᵃ / xᵇ = xᵃ⁻ᵇ)

=> 2⁰ * 5¹ / (-1)⁵⁰

=> 5/(-1)⁵⁰

// we know that if -1 is raised to power of even number the result is +1

=> 5/1

=> 5.

Answer 2

$\huge\bold{\mathtt{\red{A{\pink{N{\green{S{\blue{W{\purple{E{\orange{R}}}}}}}}}}}}}$

Step-by-step explanation:

10² *  (- 5)³ * 9⁰ / (-1)⁵¹ * (-2)² * (5)⁴

By law of exponents,  a⁰ = 1;

=> (2 * 5)² * (-1 * 5)³ * 1 / (-1)⁵¹ * (-1 * 2)² * 5⁴

=> 2² *  5² * (-1)³ * 5³ /  (-1)⁵¹ * (-1)² * 2² * 5⁴

=> 2² *  5²⁺³ * (-1)³ / (-1)⁵¹⁺² * 2² * 5⁴   (∵ xᵃ  * xᵇ = xᵃ⁺ᵇ )

=> 2² * 5⁵ * (-1)³ / (-1)⁵³ * 2² * 5⁴

=> 2²⁻² * 5⁵⁻⁴ / (-1)⁵³⁻³   (∵ xᵃ / xᵇ = xᵃ⁻ᵇ)

=> 2⁰ * 5¹ / (-1)⁵⁰

=> 5/(-1)⁵⁰

// we know that if -1 is raised to power of even number the result is +1

=> 5/1

=> 5.
