What is the standard form of the number 4.356 x 10^4?​
laiz [17]

Answer:

43,560

Step-by-step explanation:

First, let's solve the exponent value. 10 to the power 4 means that there will be 4 zeros, so the number is 10,000.

We have to multiply this by 4.356. Remember 10,000 has 4 zeros! So to make this easier, let's just move the decimal point right 4 places to get 43,560.

Therefore, the answer is 43,560.

Hope I helped!!!

scoundrel [369]

Answer:

The answer is "158.489"

Step-by-step explanation:

for san francisco earthquake:

\log(\frac{a_1}{T}) + B = 7.8\\\\\log(\frac{a_1}{T})+\log(10^{B}) = 7.8\\\\\log(\frac{a_1}{T} \times 10^{B})=7.8\\\\(\frac{a_1}{T} \times 10^B=10^{7.8}...............(i)

similarly , for coloumbia earthquake:

\frac{a_2}{T}\times 10^B = 10^{5.6}.................(ii)

divide equation (i) and (ii):

\frac{a_1}{a_2}=\frac{10^{7.8}}{10^{5.6}}\\\\\frac{a_1}{a_2}=10^{2.2}\approx 158.489
