Video Transcript

the giving expression is forest of the power to multiply it by four to the power seven. In discussion, we have to find a simplified form of they're giving expression so we know that if they empower them multiplied by areas to the power and expression so it can be written as areas to the power and plus end. Because the boat base of both numbers are same, so it can be written as in this form. So apply this identity to solve that, given its patients. So, which can Britain has forced to the power to multiplied by 40 Should about seven equals to 40 to devour two plus seven, so it becomes forest to the power nine. That means the simplified form of the given expression is forestry power nine.
