Multiply or divide. express your anwser in scienttific notation.
(7.2x10^4)x(1.8x10^3)
7.2*1.8 = 12.96
4+3 = 7
12.96 * 10^7 = 1.296*10^8
= 1.3 * 10^8 to two significant figures like the input data
To multiply two numbers in scientific notation, you multiply their coefficients and add their exponents.
(7.2x10^4) multiplied by (1.8x10^3) is equal to:
(7.2 * 1.8) x (10^4 * 10^3)
= 12.96 x (10^(4+3))
= 12.96 x 10^7
Therefore, the answer, expressed in scientific notation, is 1.296x10^8.
To multiply numbers written in scientific notation, you can multiply the coefficients (the numbers in front) and add the exponents (the numbers indicating the powers of 10).
In this case, you would multiply 7.2 by 1.8, which gives you 12.96. Then, you would add the exponents 4 and 3, resulting in a combined exponent of 7.
Therefore, the answer 12.96x10^7 can be expressed in scientific notation.
