Math Help Plz! 4 Questions

First 2 Multiply and Simplify
1. 2a(5a2 + 3a - 17)
2. -2x^2 * x^3y
3. Write the polynomial 4x^2 + x^5 - 12 + 6x in standard form
4.Simplify the expression 2^2*2^3

1. 2a(5a^2 + 3a - 17) = 10a^3 + 6a^2 - 34a answer//
2. -2x^2 * x^3y = - 2x^5y answer//
3. Write the polynomial 4x^2 + x^5 - 12 + 6x in standard form = x^5 + 4x^2 + 6x - 12 answer//
4.Simplify the expression 2^2*2^3 = 4 * 8 = 32 answer//

1. 2a(5a2 + 3a - 17) = 10a^3 +6a^2 -34a

2. -2x^2 * x^3y = -2x^(2+3y)

3. Write the polynomial 4x^2 + x^5 - 12 + 6x in standard form = x^5 +4x^2 +6x -12

4.Simplify the expression 2^2*2^3 = 4*8 = 2^5 = 32

1).
2a(5a2 + 3a - 17)
= 10a^3 + 6a^2 - 34a

2).
-2x^2 * x^3y
= -2x^5y

3).
Write the polynomial
4x^2 + x^5 - 12 + 6x
in standard form.
x^5 + 4x^2 + 6x - 12

4).Simplify the expression
2^2*2^3
= 2^5
