Multiply. write the result in scientific notation. (2.3x10^1)(7x10^6)
help pls
(2.3x10^1)(7x10^6) = 16.1x10^7 (multiply the coefficients and add the exponents) = 1.61x10^8 (convert to scientific notation by moving the decimal point)
(2.2 * 10^-3)(4 * 10^-2)
(2.2 * 10^-3)(4 * 10^-2) = 8.8 * 10^-5 (multiply the coefficients and add the exponents. Convert to scientific notation by adjusting the exponent)

simplify the expression. 8t^5 *8t^5
When we multiply two powers with the same base, we add their exponents. Therefore,
8t^5 * 8t^5 = 64t^(5+5) = 64t^10
Hence, 8t^5 * 8t^5 simplifies to 64t^10.
simplify the expression. -x(6x-7)
To simplify the expression, we need to distribute the "-x" to both terms inside the parentheses using the distributive property:
-x(6x-7) = -x(6x) + (-x)(-7)
= -6x^2 + 7x
Hence, the expression simplifies to -6x^2 + 7x.
To multiply numbers in scientific notation, you need to multiply the coefficients and add the exponents. Let's calculate it step by step:
Step 1: Multiply the coefficients:
2.3 * 7 = 16.1
Step 2: Add the exponents:
10^1 * 10^6 = 10^(1+6) = 10^7
Step 3: Combine the coefficient and the exponent:
16.1 * 10^7
So, the result of (2.3x10^1)(7x10^6) is 16.1x10^7 in scientific notation.
