Answer:
x =2.8074
Step-by-step explanation:
2^x = 7
Take the log of each side
log (2^x) = log (7)
We know log a^b = b log a
x log 2 = log 7
x = log (7) / log 2
x =2.80735
To the nearest tenth thousandth
x =2.8074
Answer:
x = 1
Step-by-step explanation:
given h(x) = 3x + 1 and h(x) = 4 , then equating
3x + 1 = 4 ( subtract 1 from both sides )
3x = 3 ( divide both sides by 3 )
x = 1
