Simplify the expression.

can anyone explain to me how to do this?

last option 32x⁷y¹⁵ is the correct answer.

Step-by-step explanation:

Identities

1). (xᵃ)ᵇ = xᵃᵇ

2). xᵃxᵇ = x⁽ᵃ⁺ ᵇ)

To find the value of expression

The given expression is,

(x²)(2xy³)⁵

Using the above identities we can evaluate the value of expression

⇒ (x²)*(2)⁵ *(x)⁵ * (y³)⁵

⇒ (2)⁵ * (x²) *(x)⁵ *(y³)⁵

⇒  32* (x²⁺⁵) *(y³ˣ⁵)

⇒  32 * x⁷ *y¹⁵

⇒  32x⁷y¹⁵

Therefore last option 32x⁷y¹⁵ is the correct answer.

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
