the exponent is the 3 the base is 2 -(29-8X3) ......i got 1
Are you trying to write 2 to the 9th minus 8 to the 3rd?
If so, write it like this: 2^9 - 8^3 (this way we know what you're asking)
If this indeed is your question, use order of operations to help you calculate. Applying exponents comes before adding or subtracting.
So evaluate 2^ 9 (2•2•2•2•2•2•2•2•2) and evaluate 8^3 (8•8•8)
You should get 512 for both of these expressions.
So, 512 - 512 leaves me with zero.
