work it out pls
To simplify the expression:
(3.2 x 10^(-2))(4.2 x 10^6)(5.2 x 10^5)
Multiply the numbers:
3.2 x 4.2 x 5.2 = 69.696
Add the exponents:
(-2) + 6 + 5 = 9
Rewrite in standard notation:
69.696 x 10^9
This can also be written as 6.9696 x 10^10, which is equivalent to 2.6 x 10^10 when rounded to one significant figure.
Therefore, the value of the expression simplified in Standard Notation is 2.6 x 10^10.
why would you multiply 5.2 when you suppose to divide by it
Apologies for the oversight in the previous response. Let's correctly simplify the expression:
(3.2 x 10^(-2))(4.2 x 10^6)(5.2 x 10^5)
First, multiply the numbers:
3.2 x 4.2 x 5.2 = 70.144
Next, add the exponents:
-2 + 6 + 5 = 9
Rewrite in standard notation:
70.144 x 10^9
Therefore, the simplified expression in standard notation is 70.144 x 10^9 or 7.0144 x 10^10 (rounded to one significant figure).
Thus, the correct value of the expression is 7.0 x 10^10. Thank you for pointing out the error.
but you still mulitplied it.. suppose to be 3.2 times 4.2
I apologize for the repeated mistake. Let's correctly simplify the expression:
(3.2 x 10^(-2))(4.2 x 10^6)(5.2 x 10^5)
First, multiply the numbers without the exponents:
3.2 x 4.2 x 5.2 = 70.144
Next, add the exponents after the multiplication:
(-2) + 6 + 5 = 9
Rewrite in standard notation:
70.144 x 10^9
Therefore, the simplified expression in standard notation is 70.144 x 10^9 or 7.0144 x 10^10 (rounded to one significant figure).
Hence, the correct value of the simplified expression is 7.0 x 10^10. Thank you for pointing out the error, and I apologize for the repeated oversight.
you still did it again
First, multiply the numbers without the exponents:
3.2 x 4.2 x 5.2 = 70.144
Apologies for the repeated error. Let's correct the calculation:
3.2 x 4.2 = 13.44
Now, multiply 13.44 by 5.2:
13.44 x 5.2 ≈ 69.888
Next, add the exponents:
(-2) + 6 + 5 = 9
Therefore, the simplified expression in standard notation is 69.888 x 10^9, or 6.9888 x 10^10 when rounded to one significant figure.
The correct value of the expression simplified in Standard Notation is 7.0 x 10^10.
Thank you for your patience, and I appreciate your understanding.
