2) 2.3 x 10-4-6 x 10-5 1.7 * 10^-4.
3) 4 x 105 +3.3 x 10 9 = 3.7* 10^6
4)7.2 x 102+5.3 x 101 = 6.02 * 10^-1
5) 9.2 x 1010 - 8.4 x 10^= -74.8*10^10

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2
