What is the area of a triangle?

The area of a triangle is defined as the total space occupied by the three sides of a triangle in a 2-dimensional plane. The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h.

From the given figure,

Height of a triangle is 8 units and the base of the triangle is 6 units.

Write the expression using an exponent:



1⋅(4/5)⋅(4/5)⋅(4/5)⋅(4/5)⋅(4/5)

Answers

Answer:

1 x [tex]4.5^{5}[/tex]

Step-by-step explanation:

The given expression can be written in exponent form as [tex]\mathbf{1 \times (\dfrac{4}{5})^5}[/tex]

What is the exponent of a number?

The exponent of a number is the power to which a number can be raised depending on its time of repetition. The way we do this generally is that we will first count the number of times a figure is repeated and raised that figure to the power of its repetition.

So from the given expression:

= 1.(4/5).(4/5).(4/5).(4/5).(4/5)

The number of times in which (4/5) is repeated is 5 times, so we have:

[tex]\mathbf{= 1 \times (\dfrac{4}{5})^5}[/tex]
