Question

9^4sqrt7 - 8^3sqrt7 + 4^3sqrt7 + 3^4sqrt7

Answer 1

is it \[9^4.............or ............9 \sqrt[4]{7}\]

Answer 2

the second one @driftracer305

Answer 3

ahh so simple:--
\[12\sqrt[4]{7} - 4\sqrt[3]{7}\]

Answer 4

this one was HARD what are you saying "easy" ahahaha

Answer 5

lol @chariety101 ......it's always like that with me...... i can solve harder ones faster than easy ones..........guess m just used to my higher lvl math thinking.....

Answer 6

Let

\[\large x = \sqrt[4]{7}\]

\[\large y = \sqrt[3]{7}\]


-------------------------------------------------------

That means


\[\large
9*\sqrt[4]{7}
-8*\sqrt[3]{7}
+4*\sqrt[3]{7}
+3*\sqrt[4]{7}
\]

turns into

\[\large
9*x
-8*y
+4*y
+3*x
\]

hopefully you see how to simplify from here
