Can you please explain how to do this? What do I do with the 4 and the 8???

=$7500(1.0075) followed by upper small 4(8) to get $9525.83...
I usually multiply the 1.0075x1.0075x1.0075x1.0074 but the (8) is throwing me off

amistre64 · Answer

the 4 and 8 most likely specify rate and time

anonymous · Answer

that 4(8) is the exponent, so instead of 4 times, multiply it 4(8)=32 times

7500(1.0075)^32

anonymous · Answer

sorry I couldn't type it right
so I multiply 1.0075 by itself 32 times?

anonymous · Answer

I there a way to do that on a calculator with out typing it 32 times?

anonymous · Answer

thats what (1.0075)^4(8) means   but (1.0075)^32 looks better
your calculator has an x^y function and that's what this is

anonymous · Answer

should look like:
$$x^{y}$$   or   $$y^{x}$$

anonymous · Answer

on the pc calc you should be able to type 1.0075^32    or    1.0075^(4*8)
