Multiplying powers with the same base you ADD the exponents:
you would then add the exponents as 2+5= 7 the answer is .
Dividing powers with the same base you SUBTRACT the exponents:
so, 5-3=2 therefore the answer would be
When you have an equation and it has brackets with a base and a exponent but also and exponent outside the brackets you MULTIPLY both of the exponents together, then add the answer you got to the base as the new exponent:
you multiply 4 by 2 to get 8, therefore is your final answer.
When you have a multiplication question in brackets with an exponent outside of the braces you can REWRITE the two bases with the exponent:
2×3 you would give both bases a 3, would equal 27 x 8= 216.
To find the power of a question that is a division question in brackets with an exponent outside you TAKE AWAY the brackets and ADD the exponent to each base:
would turn into because we add the exponent to both bases.
When you have a addition question with exponents you SUBTRACT, however when you subtract the same exponent it becomes ZERO. So, when you have an exponent of zero it will ALWAYS be 1.
you subtract 4 by 4 to get 0 therefore its .

Great use of LaTeX. 🙂
One note.. when you have 5^4 + 5^4, you need to evaluate each separately then add them together. Like this…
5^4 + 5^4 = 625 + 625
= 1250
Make sense?
