If: x/3 + 10 = 15 Then: x = 15

15 cubed = 15^3 or (3 x 10^3) + (3 x 10^2) + (7 x 10^1) + (5 x 10^0)

3 x 10 to the 5th power + 3 x 10 to the 4th power + 2 x 10 to the 2nd power

The value of 4.2 X 10 to -3 power is 0.0042

3. x= (2/10)*15 x= (.02)*15 x=3

If: x/3 + 10 = 15 Then: x = 15

15 cubed = 15^3 or (3 x 10^3) + (3 x 10^2) + (7 x 10^1) + (5 x 10^0)

3 x 10 to the 5th power + 3 x 10 to the 4th power + 2 x 10 to the 2nd power

15 x 13 = 195A simpler way of breaking this down is:15 x 13 =(10 + 5) x (10 + 3) =(10 x 10) + (10 x 3) + (10 x 5) + (5 x 3) =100 + 30 + 50 + 15 = 195

3 x (10 to power of -5) = 3/(10 to power of 5) = 3/100000 = 0.00003

1000 = 1X 10(to the power of 3) 500 = 5 x 10(to the power of 2) 30 = 3 x 10(to the power of 1) 3 = 3 x 10(to the power of 0)

3×10¹⁵ ÷ 6×10¹⁰ = (3 ÷ 6)×(10¹⁵÷10¹⁰) = 0.5×10¹⁵⁻¹⁰ = (5×10⁻¹)×10⁵ = 5×10⁻¹⁺⁵ = 5×10⁴ It is 5×10⁴ (= 50,000) times bigger.

if it's to 10 to the power of a negative, move the decimal that many places left. if it's 10 to the power of a positive, move the decimal that many places to the right. eg; 15 x 103 = 15000 15.234 x 103 = 15234 15 x 10-3 =0.0015 15.234 x 10-3 = 0.0015234 see the pattern?

13 - 2/3 (x) = 3 -2/3 (x) = -10 -2x = -30 x = 15 or 13 - 10 = 3 15 x 2/3 = 10 Answer: 15
