Question

2^x=49 is approximately 5.61 T or F?

i don't know where to start..

Answer 1

i wrote the last question wrong. @uri

Answer 2

Do you know anything about logarithms?

Answer 3

i do, but for some reason I'm drawing a complete blank..

Answer 4

Then you need to take the log of each side:
Log 2^x = log 49
X log 2 = log 49

Answer 5

There is an easier way however

Answer 6

This is arranged B-E-N (Base, exponent, number) and you just re arrange it B-N-E so it would look like:\[2^{x} = 49\]
to
\[\log_{2}(49 = x\]

Answer 7

Then you would use the change of base formula so you can plug it into your calculator\[\frac{Log(49 }{ Log(2 } = x\]
Which basically comes out to what uri said
