Calculate the powers, and do the addition. For example, the second power of 4 is the same as 4 x 4 (you are supposed to multiply 4 by itself).
It is: 2 to the power 4 times 7 to the power 2 = 784
2
What is 1+2 with sum
2 to the second power is the same as 22, which is 2 x 2 or 4.
Two over four is 2/4 2/4 cancel down by '2' == 1/2 Then appliying the second power. (1/2)^2 => (/2 x 1/2 ) = 1/4 The answer!!!!
12 to the second power is 144...2 to the second power is 4, any # to the second power is the # times itself.
16 + 49 = 60 + 5
22=2*2=4
22=2*2=4
(-4)(-4) or (-4)2
2 to the 2nd power is 4.
(-2)2 = (-2)*(-2) = +4
