45.
(2^5)/2 - (2^(3/2)) = 12
They are not! 5-3, for example is not 1/52 nor (1/5)2.
(-2/5)3 = - 0.064 -2 / (53) = - 0.016
3/2 ÷ 3/5 = 3/2 x 5/3 = 5/2 = 21/2
2/5 divided by 2/3 = 3/5
1 2/3=5/3 (2/3)/(5/3)=(2/3)*(3/5)=2/5
(3/5) / (3/2) = (3/5) x (2/3) = 6/15 = 2/5
3
Take the reciprocal of the fraction (flip it over). Then change the power to its positive equivalent.So, for example, (2/5)^-3 = (5/2)^3 = 125/8.
2 over 3 divided by 3 over 5 [2/3] / [3/5] is the same as 2 times 5 over 3 times 3 [2*5] / [3*3] 10/9 1 1/9 1.111... The answer is 1 and 1/9
No, for example: (2^5x3^2)×5=1440 260x5=1300 (under 1440) 260x6=1560 (over 1440)
2^5 x 2^3 = 2^8 = 256
