(5*103)+(3*102) = 5300

3 to the 2nd power times 3 to the 5th power = 3x3 x 3x3x3x3x3 = 2187
27/9
multiplying a number by itself is a power 2^2=2 to the 2nd power 2^3=2 to the 3rd power
43 times 32 = 576
(5*103)+(3*102) = 5300
As a product of its prime factors in exponents: 23*32 = 72

multiplying a number by itself is a power 2^2=2 to the 2nd power 2^3=2 to the 3rd power
(2)3 x (2)2 = 2(3+2) = (2)5 (8) x (4) = 32
(3^2)^3 is 3^()2x3=3^6
Well, darling, when you have the same base and you're multiplying exponents, you just add the exponents. So, 3 to the 7th power times 3 to the 3rd power is 3 to the 10th power. Simple math, honey.
