What is the value of the expression?
–83 the three is an exponent

Value of an expression 83
in where 8 is the base number and 3 is the exponent.
To get the answer, simply multiply the base number as many times as the exponent says.
Since the exponent is 3 and base is 8, we need to multiply 8 three times.
=> 8 x 8 x 8
=> 512
Thus, the value of the given equation 83 is equals to 512
to check if our answer is correct, simply divide 512 by 8 twice.
=> 512 / 8
=> 62 / 8
=> 8

This polygon has 4 sides
180(4-2) = 180(2) = 360 degree
80+90+2x + 3x = 360
170+5x = 360
5x = 190
x= 38
measure of angle t is 2(38)= 76
the answer is c. trust me
hope this !
