The measures of two sides of a triangle are 7.3 centimeters and 2.94 centimeters. The triangle's perimeter is 14.8 centimeters.
evablogger [386]
The perimeter is the sum of all lengths of the side of a polygon. For a triangle it is expressed as:

P = a + b + c

We let a = 7.3, b = 2.94 and c=x

Therefore, the perimeter of the given triangle is:

14.8 = 7.3 + 2.94 + x

From the options given, the correct answer is the last option. The expression, <span>x - 14.8 = 2.94 + 7.3, will give an erroneous value of the third side. It will be more than the perimeter given.</span>

Which is the simplified form of the expression (6^-4)^-9/6^6
natima [27]

Given expression: \frac{((6^{-4})^{-9})}{6^6}.

First we would apply exponents of exponent rule on the top.

(a^m)^n= a^{m\times n}

Therefore,

((6^{-4})^{-9}) = (6)^{-4\times -9} = (6)^{36}

=\frac{((6^{-4})^{-9})}{6^6} = \frac{6^36}{6^6}

Applying quotient rule of exponents.

\frac{a^m}{a^n} = a^{m-n}

Therefore \ \frac{6^{36}}{6^6} =6^{36-6}

= 6^{30}

<h3>Therefore,  6^{30} is the simplified form of the expression \frac{((6^{-4})^{-9})}{6^6}.</h3>
