Answer:
The answer to your question is: d) 0.46x10^-4
Step-by-step explanation:
(1.15x10⁻⁷) / (2.5x10⁻³)
First, divide 1.15 by 2.5 1.15 / 2.5 = 0.46
Second, subtract the power -7 - (-3) = -7 + 3 = -4
Finally, express the number 0.46 x 10⁻⁴
a) 4.6x10^-10
b) 0.46x10^-3
c) 4.6x10^-3
d) 0.46x10^-4
( 11 + 33 - 4^2 ) / ( 8 - 4 )
( 11 + 33 - 16 ) / ( 8 - 4 ) 4 to the power of 2 -> 4 times 4 -> 16
( 44 - 16 ) / ( 8 - 4 ) 11 plus 33 is 44
28 / ( 8 - 4 ) 44 subtracted by 16 is 28
28 / 4 8 subtracted by 4 is 4
7 28 divided by 4 is 7
7 is the answer
