Evaluate the expression 32 Evaluate the expression 53 Evalua

Evaluate the expression. -3^2 Evaluate the expression. (-5)^3 Evaluate the expression. -(2/9)^2 Evaluate the expression for s = 10, t = -2. s^2 - 2t^3 Simplify the expression. Write the answer in exponent form. t^7 middot t^6 Simplify the expression. Write the answer in exponent form. z^13/z^6 Simplify the expression. Write the answer in exponent form. x^2x^6/x^5

Solution

a) this can be written as -3*-3 = 9

b) this can be written as -5*-5*-5 = -125

c) this can be written as -(4/81) , as 2*2 = 4 and 9*9 = 81

d) so putting the values 10^2 - 2*(-2)^3 = 100 - 2*(-8) = 100+16 = 116

e) when same base are given , we can add the powers for multiplication hence the answer would be

t^(7+6) = t^(13)

f) for division , we substract the powers

z^(13-6) = z^(7)

g) so first we add then we substract

so we get

x^(2+6) = x^8

and then x^(8-5) = x^3
