Question

simplify 
5^4√7-8^3√7-2^4√7-^3√7

agreene · Answer

$$5^4\sqrt{7-8^3}\sqrt{7-2^4}\sqrt{7-1^3}\sqrt 7$$

Is that the question? it's hard to interpret what you mean without parenthetical/bracketed statements.

anonymous · Answer

no.
its exactly how it looks .

agreene · Answer

$$5^4\sqrt 7 -8^3\sqrt 7 -2^4\sqrt7 -1^3\sqrt7=96\sqrt7$$

anonymous · Answer

thats what i got but these are the answers: 
3^4√7-9^3√7
-6√14
-6√6
3^4√14-9^3√14

agreene · Answer

O_o none of those are even close... they are all negative. and are around
~1,000.001  ish in decimal...

anonymous · Answer

i donnnno

agreene · Answer

me either :X

anonymous · Answer

well the last part is -^3√7 not -1^3√7 ? if that makes a diff

anonymous · Answer

The 1st answer is OK. Need to rite expression differently:$$5\sqrt[4]{7}-8\sqrt[3]{7}-2\sqrt[4]{7}-\sqrt[3]{7}$$$$\sqrt[4]{7}(5-2)-\sqrt[3]{7}(8+1)$$$$\sqrt[4]{7}*3-\sqrt[3]{7}*9$$$$3\sqrt[4]{7}-9\sqrt[3]{7}$$
