2.7 times 10 to the -4 power in standard form

Solution:

Given is:

We have to write in standard form

Standard form means writing the very large or very small numbers easily

From given,

The exponent of 10 is -4

Exponent is negative

Which means, the decimal point is to be moved to left when converting the number to standard form

Therefore, move the decimal point towards left 4 places

Thus the number is written in standard form

a)

V=p+prt

now we solve for P

V=P (1+rt)

Divide both sides by (1+rt)

P=V÷(1+rt)...answer

b)

P=V÷(1+rt)

P=3,000÷(1+0.06×5)

P=2,307.69
