product rule
x^a *x^b= x^(a+b)
x^a/ x^b=x^(ab)
1.) Calculate 5.91 x 10^3 times 2.3 x 10^8 by using scientific notation and the product rule.
= 5.91*2.3*10^3*10^8
=13.591*10^(3+8)
=13.591*10^11
=1.3591*10^12
2.) Calculate 8.51 x 10^8 divided by 4.7 x 10^3 by using scientific notation and the quotient rule.
=8.51/4.7 *(10^8/10^3)
=1.8106*10^(83)
=1.8106*10^5
Please let me know if you need any clarification. I'm always happy to answer your questions.1.) Calculate 5.26 x 10^3 times 7.73 x 10^5 by using scientific notation and the product rule
=5.53 *7.73 *10^3*10^5
=42.75*10^(3+5)
=42.75 *10^8
=4.275*10^9
. 2.) Calculate 4.74 x 10^10 divided by 9.55 x 10^5 by using scientific notation and the quotient rule.
=4.74/9.55 * 10^10/10^5
=0.4963*10^(105)
=0.4963*10^5
=4.963*10^4
