10 to the fifth power x 10 to the negative fourth power x 10 to the elevnth power
To simplify this expression, we can use the rule of exponents which states that when multiplying numbers with the same base, you add the exponents.
10^5 * 10^(-4) * 10^11 = 10^(5 + (-4) + 11)
Now, let's simplify the exponents:
= 10^(5 - 4 + 11)
= 10^(12)
Therefore, 10 to the fifth power multiplied by 10 to the negative fourth power multiplied by 10 to the eleventh power is equal to 10 to the twelfth power, written as 10^12.
