Hello,
2.0 x 10^-4 * 3.1 x 10^-20
Apply exponent rule:
a^b*a^c=a^b+c
= 10^-24
=2*10^-24 * 3.1
Apply exponent rule: a^-b=1/a^b
:10^-24=1/10^24
=2*3.1*1/10^24
Multiply fractions:
a * b/c = a*b/c
=3.1*1*2/10^24
Apply rule 1* a = a
=3.1 * 2/10^24
2/10^24=1/5^24* 8388608
Multiply fractions:
= 1 x 3.1/5^24 x 8388608
Apply rule 1* a = a
= 3.1/5^24 x 8388608
Covert elements to decimal form:
5^24= 5.96046...E16
Multiply: 5.96046...E16 * 8388608
= 5.0E23
= 3.1/5.0E23
Divide:
3.1/5.0E23=6.2E-24
Simply:
6.2 x 10^-24
Faith xoxo
