Question

There are 5^12 blades of grass in each acre of land, and a section of land has 5^4 acres of land. How many blades of grass does the land have?

Answer 1

Answer:

5^16

Step-by-step explanation:

total acre of land = 5^4

total blades of grass in each acre of land = 5^12

total blades of grass land have= 5^12 × 5^4

= 5^ (12+4)

= 5^16

((if base are same and in multiply then powers will be add))

Answer 2

Answer:

$each \: acre \: of \: land \: has \: 5 {}^{12 } blades \: of \: gras$

$so \: \: 5 {}^{4} acres \: of \: land \: have \: blades \: of \: grass$

$= 5 {}^{12} \times 5 {}^{4}$

$= 5 {}^{12 + 4} blades \: of \: grass$

$= 5 {}^{16} blades \: \: of \: grass$
