+log%28x%5E3%29%2Blog%28x%5E27%29+=+4
+3%2Alog%28x%29+%2B+27%2Alog%28x%29+=+4+
+log%28x%29%2A%28+3+%2B+27+%29+=+4+
+30%2Alog%28x%29+=+4+
+log%28x%29+=+2%2F15+
+x+=+10%5E%282%2F15%29+
+x+=+1.359+

check answer:
+log%28x%5E3%29+%2B+log%28x%5E27%29+=+4
+log%281.359%5E3%29+%2B+log%281.359%5E27%29+=+4
+log%28+2.51+%29+%2B+log%28+3952.99+%29+=+4+
+.3997+%2B+3.597+=+4+
+3.997+=+4+
I think the error is due to rounding off
